Hi guys
I have a question about the understanding of Photodetector in photovoltaic-mode and their cut-off frequency. The frequence limited by the capacity of the Photodiode (example a PiN) and by the size of the load impedance.
So it is possible to have a cut-off frequency at some MHz? In the most Applicationsnodes, they talk about 200-350 kHz. Is there something i forget, for example to take account of the carrier transport in the semiconductor?
Regards,
Tim
